Electric hair-waving apparatus



L. R. KOEGEL ELECTRIC HAIR WAVING APPARATUS Filed Feb. 27. 1923 LOUIS ROBERT IKOEGEL, 0F TOURS, FRANCE.

ELECTRIC HAIR-WAVTNG APPATUS.-

Application filed February 27, 1923. Serial No. 621,600.

To all whomz't may concern.

Be it known that I, LoUis ROBERT KOEGEL, a citizen of the French Republic, residing at Tours, Indre-et-Loire, France, have invented certain new and useful Improvements in Electric Hair-Waving Apparatus, of which the following is a specification.

This invention relates to waving appara.

tus for use by persons without the training of a hair-dresser capable of giving quickly to the hair a wave as. lasting and beautful as that obtained slowly with ordinary curling tongs.

The frame of suitable shape is heated electrically and the hair rapidly and'readily wound thereon.

The heating resistance is placed inside this frame which is formed with a handle and switch for the electric current.

Such a paratus being compact and capable of belng used anywhere where there/1s electricity can be, readily employed when travelling without the assistance of a specialist. A specialist even if he possesses a numerous clinetele may reduce his stafi since he can ive a wave as yielding, elegant and lasting in a shorter period.

The accompanying drawing shows by way of example one type of hair waver.

Fig. 1 is a side view of the device partly in section.

Fig. 2 is a longitudinal section on line 2-2 of Fig. 1.

Fig. 3 is a section showing the application of the waving apparatus applied for producing a permanent wave.

The apparatus illustrated Figs. 1 and 2 consists essentially of a hollow central tube a of elliptical shape carrying on its sides cylindrical projections 6 arranged alternately and regularly s aced.

. Inside this tube a is oused the frame e of the electric resistance for heating the apparatus consisting of as many elements d as there are projections b; or only one central element may be used, and the pro ections 12 heated by conductibility.

The tube a and frame 0 are mounted in a hollow handle 6 in which the terminals f and switch 9 are housed. The switch 9 allows the current to the heating resistance to be cut off as desired. I

To protect the head against burnswluch might occur if contact were made with the apparatus the opposite end to the handle is during eating.

provided with a pad of rubber h or other material of poor heat conductivity.

The waver is employed in the following way :The hair i is passed through an elas tic band or nippers which fits a groove in the rubber end it which is placed against the head. The hair is then wound around the central tube a being passed over the projections b alternately.

An elastic band or nippers similar to the first holds the hair against the apparatus.

When this preliminary operation has been effected the switch knob g in the handle is moved to the on position. At the end of one or two minutes the heating may be cut off by pressing the switch in the opposite direction or by releasing it.

The withdrawal of the hair from the ap paratus is effected by removin the elastlc band or nippers and unwin ing it. As many locks of hair as desired may be easily and readily waved so that. all types of coiffuremay be effected with the help of this apparatus without the requirement of any separate source of heat.

Moreover this apparatus does not make the hair frizzy and consequently does not render it brittle when it is being brushed.

Owing to its moderate heating this electric hair waver does not discolour fair or plasily whatever the colour or texture of the air.

To obtain a permanent wave the apparatus is arranged as shown in Fig. 3, in which the resistance is placed outside of the frame a and the projections b around which is wound the lock of hair i to be waved. This lock is surrounded by a band saturated with a solution of borax or other suitable solvent to revent the hair from becoming dry The waving apparatus, the length of which may be reduced or .enlarged accord- .in to the length of the hair, is housed insi e a copper socket is heated by an exterior resistance Z and surrounded by an insulating cover m and a case n of copper or other suit-- able material.- A diaphragm 0 similar to that employed in photographic apparatus, when open allows the waving apparatus a, 6,; to be inserted into-the socket is. When the diaphragm o is closed again and the interior temperature maintainedv it prevents a too rapid evaporation of the borax solution.

What I claim and desire to secure by Letters' Patent is 1. An electric hair waving a paratus consisting of "a hollow tu'be rovi ed with projections round which the air is wound, and an electric heater arranged inside the tube.

2. An electric hair waving apparatus consisting of a hollow tube provided with projections round which the hair is wound, an electric resistance coil arranged inside the hollow tube, a handle provided with a switch to put the resistance in circuit, and a pad of poor heat conductivity at the other end ofithe hollow tube.

menace 3. An electric hair waving apparatus consisting of a hollow tube provided with projections round which the hair is wound, an electric resistance placed outside in a copper socket in which the hollow tube is arranged, means for closing said socket, an insulating covering for the socket, and a pad of poor heat conductivity at one end of the hollow tu e.

In witness whereof ll 'afix my signature.
